A lot of the music mentioned in the thread doesn't warrant guilt. Take ABBA: why would anyone feel guilty about listening to some of the most sublime pop music ever recorded?

I listen to loads of cheesy pop songs that could be regarded as a guilty pleasures, but I don't feel guilty about it. If there's something about a song that makes me want to listen to it then it's too good to feel guilty about.

I suppose my guilty pleasure is listening to music I actually don't like and trying to work out why it's shit.

See - this is my point. I love Cyndi Lauper. Absolutely fucking love her. I think her voice is amazing and I love the '80s production values. I think that Time After Time is one of the most beautiful songs ever written and recorded. Why would I feel guilty about listening to good music? Just because most of what I listen to is metal or hardcore and that doesn't fit in with it?
